FRANK KUHN AND J' AY A. HAND, 0F DETROIT, VMICHIGAN, ASSIGNORS TOAMERICAN ELECTRICAL HEATER COMIANY, 0F DETROIT, MICHIGAN, A vCORPORATION 0F Mr cHIGAN.

To all whom t may concer/n.' .A Be itknown that we, FRANK KUHN and JAYA. HAND, both citizens of the-'United n '5, 6, 7 and 8 are carried by aframe 11,

States of America, `residing at Detroit,in

the county of Wayne and State of Michigan,

have invented certain new and useful Improvements in Machines forMoistening Ad-v hesive Tape, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to machines for moistening adhesive tape.

In devices of this character 1t is common to provide for feeding thetape from a reel in suche manner that its coated surface will havecontact with a roller partially imever, that the water if cold does notact rapidly enough to dissolve the adhesive coating so that 4the tapedoes not always stick firmly to the surface to which it is applied'after being drawn from the machine.

It is the object of this invention to provide means for 'electricallyheating the' water applied to the coated surface of the tape -so thatthere will be an increased vsolvent.

action on the adhesive resulting in an imme diate softening of thecoated surface so that the full efficiency thereof may be derived.

In the drawings:

Figure 1 is a view of the machine inside; elevation and partial section,the normal,

position of the tape being shownv in full lines and its position whenbeing drawn over the moistened roller being indicated in dash lines Fig.2 illustrates in perspective a modified form of the heater shown in Fig.1; n Fig. 3 illustrates another modied form o electric heater.

The reference character 1 designates the base of the machine and 2 is acircular 4casing mounted upon said base and receiving adjustable betweenthe .full lines and dash lines -1n Fig. 1, the roller It has been found,how-l MAcHINEEoEMosTENmG ADHESIVE TAPE.

*drawn over the roller 9 which is partially immersed in a body of wateror other liquid contained by a tank 10. The guide rollers pivot'allymounted as 'indicated at 12 and os1t1ons, shown in 8 being spaced fromthe roller 9 in the former or normal position and being shifted y intocontact with said roller 9 in the latter position of said frame toinsure rotation of the roller 9.

. `In the tank 10 there is, immersed an elec- `tric heater 13, thedetailed construction of which is no feature of the present invention,

-said heater being mounted in an end wall of saidtank and havingconnection exteriorly of the tank with a metallic tube 14 through whichthe conductors supplying current to the heater are led to a socket'member 15.

In the modification illustrated in Fig. 2

the heating element 16 is interiorly secured to the bottom of the tankby bolts or rivets 16H, while Fig. 3 shows an arrangement wherein theheater 17 is exteriorly secured to the bottom of the tank.

What we claim as our invention is 1. .The combination with a mountingforaJ reel vof adhesive coated tape, of a tank for i receiving a body ofliquid, means for applying sa1d liquid to the coated surface of the tapeas the latter is drawn from the reel, an

electric heater permanently associated with said-tank, anda metallictube yextending lfrom said heater exteriorly of the tank and terminallycarrying a socket member.

2. The combination with a mounting for la reel of adhesive coated tape,of a tank for receiving a body of liquid, an electric heater immersedwithin said tank and secured to an en'd wall thereof, and a tubularmetallic receiver for conductors extending to said heater. f

In testimony whereof we affix our signatures.
